Operation
6.1.7 Performing a control measurement
At the end of the commissioning, you perform a control measurement to check
the metering pumps and the metering valves for correct operation.
1.
Select the recipe you wish to work with from the Overview window in the
control system.
2.
Perform all work steps as described in chapter 5.4.13 on page 47.
6.2 Coating
Prior to coating, the unit must always be put into operation (see chapter 6.1 on
page 59).
1.
Set a low air inlet pressure on the metering pump air pressure regulator.
2.
Press the
F 2
function key on the control module to switch the unit to spray-
ing mode.
Observe the operating mode display. When spraying operation has started,
the operating mode initially displays “Filling” and then changes to “Spraying”
as soon as the spray hose is filled with material. Only then the unit is ready
for operation.
3.
Keep spraying the flushing agent residues in the system into a collecting
vessel until clean material starts flowing out.
4.
Adjust the air pressure regulator on the metering pumps to the optimal
spraying pressure.
The metering pumps for the B-side components must have have an approx.
0,5 - 0,8 bar higher air inlet pressure than those for the A-side components
to enable feeding the hardener. The pressure difference from A to B can be
adjusted at the pressure controller for the A component metering pump (see
chapter 7.4.4 on page 70).
6.2.1 Adjust spraying pressure
Please observe the following information when adjusting the spraying pressure:
➤
Optimal spraying pressure is indicated by a uniform application of material
with fading out peripheral zones.
➤
Operate the unit only with an air pressure as
high as necessary, to achieve a good atomiza-
tion at the recommended spraying distance of
approx. 30-40 cm.
➤
Too high spraying pressure causes increased
material consumption and paint mist.
➤
Too low spraying pressure results in the
appearance of stripes and differences in the
coating thickness.
30-40 cm
